Taco 120-13 Cast Iron Circulator Pump 1/6 Hp 115V

Product Description

The TACO 120-13 is a single-phase cast iron circulator pump rated at 1/6 HP and 115 volts, designed for closed hydronic heating and cooling systems. It uses a resilient-mounted, split-phase motor running at 1725 RPM with a built-in overload protector to guard against motor burnout. The pump features a one-piece dynamically balanced impeller, a stainless steel shaft, and a two-piece carbon and ceramic seal assembly for reliable, long-service operation. Sleeve bearings support quiet operation. A durable one-piece spring coupling connects the motor to the pump end. This unit ships with 2-inch flanges and is installed by licensed plumbers and HVAC hydronic technicians.

The 120-13 is suited for residential and light commercial hydronic applications including hot water baseboard heating systems, radiant floor loops, and chilled water distribution circuits. The 2-inch flanged connections accommodate standard iron pipe installations. This pump fits closed-loop circulating systems where a compact, reliable single-phase unit is required. It is a direct OEM-style replacement for existing TACO 120-series circulator installations.

Key Features

Compatibility

Designed as an OEM-style replacement for closed-loop hydronic circulator applications requiring a 2-inch flanged, single-phase pump in the TACO 120-series form factor.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic technician. Shut off system water supply and relieve system pressure before removing the existing circulator. Drain the affected loop to prevent spillage during flange removal. Follow local plumbing codes, including applicable IPC requirements, for pipe connections and pressure testing after installation.
